For high-flow, high-pressure feed pumps, which type is better?
Thread Content
Process conditions: 3-5 m3/h, outlet pressure 5-10 MPa; a relatively stable flow rate is required. I’m not sure which pump would be the best choice?
Your conditions are incomplete; a selection cannot be made. The inlet pressure is unknown, the net positive suction head is unknown, the temperature is unknown, and the medium is unknown
For such low flow rates, a diaphragm pump can be used, or a partial-flow pump can also be an option, although its efficiency is very low.
Imported at atmospheric pressure; no high requirements regarding cavitation margin. The outlet temperature is at room temperature, and the medium is propylene
For a pump with a flow rate of 3–5 m3/h, such a small reciprocating pump only needs a return control mechanism； You might also consider choosing the Sichuan Nikki jet grouting pump; it’s not expensive and quite practical.
Such a high head – it must be a reciprocating pump

With such high pressure and a need for stable flow, use a rotary shell pump – that is, the rotary jet pump mentioned above, also known as a pitot tube pump. In addition to Japanese aircraft, Seals are also produced. You can give it some thought. . . But as far as I know, the price isn’t cheap.
Low flow rate, high head – reciprocating pumps should be suitable
